This invention relates to oilersxand particularly to oilers oi the pressure-discharge t e. t t Signe of the objects oftheiinvention is the A5 provision or" an oiler thatfcandbeV operated alternatively inl the same manner as an ordinary pressure oiler,.by pressure applied bel tween theplunger handle and the reservoir, Vor by pressure transmitted to the plunger lo handle'through the spout of the oiler byjpress. ing the latter against theobject to. beoiled.

n y Another object ofcthe inventionis the pro- (r-Gof Figure 5 showing the'hmgedconvision, in the bodyor `reservoirof the oiler, of a-.plung-er 'cylindersupported by a univvi .3 versal connection Y atrone` end,and otherwise solely supported ,by the Eplunger itself, .so that the cylinder accommodates Y itself to .slight .misalignment .of the plunger frod, thereby avoiding binding and permitting the La use Withoutundue l friction, yof aplunger rod i of uniform diameter throughout.

Still another obj ect of r`the linvention is ,the I novel pump construction, theV samef comprising a valved fitting rigidly.supportedand ,o 25 the plunger cylinder connectedto said valved `fitting byva sealedball joint. i

`vfurther objectof the inventionl is t0 pro- `vide a valved partition adjacent thevforward end of vthe zreservoir ,forming .an ,anterior v m30 `chamberintersected by the valved fitting for trapping a bodv of oil, makingfit accessible t tothe pump when the oiler is pt )sitionedspoutv upward7 ysaid partition constituting f at ,the-

same time-*an inboard support Jfor thelvalved fitting making the .mounting of this member absolutely rigid,vthis being an .essentialactor in adapting the construction to transmit the operating pressurethrou-ghthe spout to the plunger rood.

',340 Other objectsvof the invention will appear as the followingl description of a preferred embodiment thereof proceeds.

Figure 8 is a perspective vieW of the hinged valve,` .a part of the partition itself being-also shown ligureQis a perspectiveview of the in-l A65 ner end of the plunger cylinder; and y Figure,V l0 is .cross sectiontaken along the line 1'0-10 ofFigure l. y

Referringinovv in detail to the-several figluresthefoiler comprises a body or reser-l 70 Voirl constitutedlpreferably by a cylindricalli side Wall 2 having inner and outer head- .ers `3 and 4,*respectively.' A bolt 5 passes preferably .axially through the reservoir having its head and nut engaging the outer faces 75 ofthe headers for holding the latter rigidly imposition. lSuitable oil-tightfgaskets 6 .are compressedbetween the edges of the cylindric'al member 2 and the inner face lot' the headers.l 80

A4 disk-like partition 7 is arranged in the kreservoir,adjacent its anterior end and detines iachamber of relatively small size in Whicha body of. oil istrappedr-and retained so astofbe available for pumping when the 85 oiler is positioned Y`With its yanterior end upper-most. For :the l purpose ofi trapping and retainingthe oil, theV partition as shown in yFigures Afto 7 is provided .With yan opening forgportf,closed ,by a hinged che'clr valve'9, '90

i "71:10" cylindery 17 enables a ver c, the klatter opening toward the restricted u chamber.

VAlthough the specific construction of the jvalve 9 is vai relatively mino-r part of the invention, yet `at this point it may be stated that the partition 7- is formed with a slot 10 and a lug 11 at the central part of said slot, pressed out from the material of said partition on the side of the partition opposite the valve. The valve 9 is formed with two pairs of lugs 12 and 13, all four of said lugs being passedthrough said slot towardthe side of the partition opposite theV valve and then being bent to the position shown in Figures 15 r.and 8'so as to prevent their withdrawalfrom i v the slot. The lugs 12 act as a limit stopto 'the opening movement of the valve j; f

The oder is provided with d handle 1i suitably secured tothe header .Q4 and extend?" l.ing preferably above the axis of the reservoir, `leaving room" below saidih'andle` for the plunger rod 15. u Y L ,Y l i f1 l plunger rod operates through :a stuff- ."inggland l'inlthe header 4 and in coopera- 5htion with `a pumpcylinder 17. 'Ihe'p'lunger rod'is vnormally'retracted by meanssuch as p thespring 18 which expands between the end ``of' theicylinder 17 and a collar' 19" fixed to n the plunger rod.'vr The cylinder '17 is mount- "go-ed by'meansof aiiuid-tight ball joint 20 in A the end of a valved fitting 21,`the latter being Y' rigidly supperteda ,i f

' 'Bynthisconstruction the'cylin'der'l'i can rocl'r'slightly anyk direction about the ball joint so as'to preserve its conditiony of'align- VAmentwith the plunge'rlrod 15., regardless yof any slight misalignment of the plunger rod,

- either incident to its construction or'throughl the pressure in its use.l The flexibility of the n y `cheap construc- "tion ofplunger rod to be e ciently used, since the-plunger rod may be 'made of plainwstock of uniform diameter throughoutwithout unf 'due friction or binding in the cylinder.

515,".` having-'the plu'nger'rodA of uniform di- "raineter through af great` extent r of itslength,

farsealing'j oint of extensive length is. provided thecylinder 17 permitting considert" able tolerance between the cylinder yand y50p-"plunger rod without the risk of loss ofv pressure. ByjthisV means, wear ofthe coacting 'faces yof, the cylinder? and plunger rod isminlong life of the oiler thus ash ..sure'd'ni' .1 n Y' e 55 l n rIfhe valved fittingy 21 is supported lat' one *end'by'theheader 3 and yat the other end by n the/partition' 7, the latter having a" hole. 22, F1guref7,finto whichthe valved fitting extends.v Said fitting is formed at its outer end 'i fttingrat thetouter end securing the fitting in .tplaceI On account ofthe fitting having a ,supportjatf'each end', itis'supported with exl with a shouldern abutting the header 3 and a Vnut-23 screws" upon theadjacent lend of saidY municated to the ball end of the cylinder 17 'i in the use of the oiler.

The outer end of the fitting 21 is furnishedVv with a spout 24C and Ya gland 25 the latter havupon the gland 25 and against the ballend 27 so as to seat the latter in a'fluid-tight manner in its seat within said gland. The opening inthe ring nut is slightly larger than the diameter of the tip where VitL passesthrough the ring nut thus permitting a limited amount of universal movementb'etween the tip and the'spout. Thus the tip maybe made'to align itself with-oil holes-which are `not in exact paralleliennV with the'axis of the oiler. 1 Theqvalved fitting 21 is provided with an inlet check valve 30 and an outlet check valve 31. The vinlet check valve`is very close to the lower wall of the restricted chamber Hformedgbetween" the partition v7`and header 3 *sothat'thepump will suck 'practically the last .drop of Voil jin the restrictedl chamber. v The inlet Vvalve/is Ypreferably seatedI in a Vcage y3.2 mayv bereinoved for YCleaning "or replacement, andl the outlet valve'is r'etained ina Vvalvechamber in the endl of the ,.spout Ifrom thev'alved fitting, the spider and' the valve ymay be readily-'taken' out.

" In iordertoprevent possible rotationy of the i entire bodywor rbarrel of the gunabout the 'X axis of the plunger,when'thev handle 14 is not j held, itis advantageous toprovide a yolre 35 l, 'clamped tothe plunger rod at a suitable point vv.within'the.body [and having 'the'fsides thereof .f V'tive thereto.

y that the oileifhiaybeoperated in either of two f ways,f'fir`st-`in a manner' well known inollers,

` thatiis tosayfby squeezingthe plungerhanembracing the 51 anldfreely slidable relaj` iv` dl'eand the handle of the reservoir together,

thus depressing the plunger. Inlthi's mode of operation, there isv no strain upon the spout,

valvedffitting' or Vthe plunger cylinder 17. The other modeof operation which is known in respect to heavy grease guns, but has noty ,heretofore been successfully"practiced lwith `fr iliquidfoilers, isV to restthe tip vagainst the wallv Iof the .aperturegto be oiled and then to pressy j Lagainstfthe plunger rhandle without holding .Kthe'reservoir handle. In this instance, Apressure is transmittedthrough the tip, spout and cylinder, and kin the absence of special pro* u visions for resisting this pressure thrust, Ythere is aptto be a deflection between the e plunger rod and cylinder` causing: binding ,be-

tween the parts' andu also a tendency of the valvedfitting to be deflected, resulting even-V lioA tually in a loosening ofthe joint between the valve and the outerfheading. I
